Very cool find, especially for $8! I hope it lasts, I’m generally a bit skeptical about fancy features like wifi control in devices like light bulbs.
The fact that Opple 3 reads the 5000K as 100CRI does indicate very good light quality, though it should also raise some eyebrows as the actual incan only registers 98CRI. Would be nice to have a spectrogram and see whether the emission has a blue spike, or has a smooth region like BridgeLux Thrive and some Feit Electric bulbs I got from Costco.
Also, the CCT reading for halogen is way off at 3742K, considering that tungsten melts at 3695K…my own halogen bulb appears to be within 50K of an SFT40 3000K driven at around 1A. This gives me serious trust issues with Opple devices.
Interesting to see that the halogen has a much smoother, sinusoidal waveform, presumably due to the thermal inertia.
its cheap enough for entertainment, and if I hate it, I can return to Amazon.
So far, Im inclined to keep it. I like the option to use the scheduling feature. For example, to automate lights on, lights off, in some parts of the house, such as when Im traveling.
I confess I still want a new Flicker Free Photo Grade LED bulb from Waveform. My last one burned out after 3 years, and my wallet has refused to give me another $28 plus shipping to replace it.
They’re good bulbs, Tapo is the name used by TP-Link to market them. My daughter has had one in her bedroom lamp for probably 12mths plus and it’s still working fine. It’s good to see the light output specs are excellent.
I bought a couple more a month back for a light. But that light’s bayonet fitting (Australian spec B22) has not been made to normal specs- so they can’t be inserted fully to latch into the bayonet. I need to “modify” the light a bit (insert swear words).
